Patent No. 522,326, dated July 3, 1894,

Application filed November 14,1893. SerialNo. 490,949. (No model.)

To all whom, it may concern: 7

Be it known that l, J EANNOT W. KENEVEL, a citizen of the United States,residing at Ohicago,1n the county of Cook and State of Illinow, haveinvented a new and useful Improvement in Gas-Making Apparatus, of whichthe Myinvention relates to an improvement in apparatus for manufacturingproducergas w1th the employment of superheated steam; and the object ofmy invention is to provide an apparatus for the purpose named whichshall operate very economically to generate a superheat the steamemployed in the manufacture of the gas, and also for working a pump bywhich to feed the boiler, by the heat from the products of combustion ontheir-Way from the fuel-chamber to the discharge-flue.

My invention consists in the construction and combinations of partsforming my improved apparatus. The accompanying drawing represents myimproved gasmaking apparatus by a' partly broken view in longitudinallysectional elevation. v

A denotes the fuel or generating chamber, having a covered stoke-hole rin its front wall and from near which extends a grate B, preferablyinclined, as shown, with its inner end resting on a support'S, betweenwhich and the rear wall of the fuel-chamber, but on a plane lower thanthat of the grate S, is a supplemental grate B over the ash-pit B fromthe base of which leads the clean-out opening 7'.

Behind the. chamber A, and communicating with it through a passage q, isa checkerchamber A in which to fix the gas on its way from thegenerating-chamber to the outlet 19 at the base of the checker-chamberand bywhich the gas-product is led to the point of storage or use; andin the chamber A are built the perpendicular, relatively overlapping,partitions o and 0, which extend across the chamber, respectively, fromthe top and bottom but short of the lower and upper sides to affordoanirregular passage through it and thereby retain the products ofcombustion the longer in their course to the outlet.

0 is a boiler formed, by preference, of a reservoir 12 housed in theupper forward corner of the chamber A, and of the two smaller reservoirs'n' and n having free communication with each other and supported oneabove the other on a shelf m extending fromtherear wall of thegenerating chamber; the reservoirs, thus at opposite sides of thechamber, being exposed to the heat of the products of combustion thereinand connected by tubes 12, which thus extend across the path of theproductsof combustion to the passage q. The advantage in forming theboiler in sections, so to speak, placed at opposite sides of thefuel-chamber is that the extent of surface to be heated is the betterexposed to the heating.-

medium; and the advantage of forming the inner of the sections in thetwo reservoirs n and n is that they may be placed one above the other toextend less far over into, and present the less obstruction in the pathof the products of combustion, than if they were in one, like thesection at, though their joint capacity may correspond with the capacityof the latter.

The steam-dome n has connected with it a conduit 1 containing a shut-offvalve Z, from which a pipe 1 provided with a valve Z leads into theupper end of a steam-superheating drum D, extending vertically throughthe checker-chamber A. The conduit Z is shown broken away at one end toindicate that it .may lead to other points also, if desired, as

to feed water, through the pipe h, into the boiler O.

From the lower end of the superheating dea vice I) extends a pipe g,containing a valve g and leading to a head f, whence proceeds a branch fabout the chamber above the grate B, in the wall thereof and of thesupport S, and having steam-jets f directed into said chamber. off valvef connects the head f with a pipe A pipe f containing a shut- I 9"containing a valve 9 and which is shown broken at its upper end toindicate that it leads from a hydrocarbon oil supply (not shown). Fromthe pipe 9 there leads 'a branch e containinga shut-0d valve e, aboutthe upper end of the drum D, where are provided the oil'jets a directedinto the checkerchamber at'the opening 0 in its top through which thedrum extends.

The apparatus, constructed as described, while it may be used with coalin any form, is particularly adapted for the use of coalslaek, forfeeding which I provide a holder II, having a hopper bottom from whichextends a chute cl through the front wall of the chamber A above thegrate B.

The products of combustion from the burning fuel in the generatingchamber A (and which is supplied with coal from the holder H) ascendtherein, heating the boiler O to generate steam, and pass into andthrough the retarding passage in the checker-chamber A to the outlet 1).Steam from the dome 91 works the blower F and the pump G 5 and somepasses through the drum D wherein it is superheated by the'products ofcombustion and heat in the checker-chamber. The su perheated steam isinjected with oil from the pipe g into the chamber Anear the grate Bthrough the jets f and oil is injected through the opening 0 into thechecker-chamber, to act upon the products of combustion therein, whichescape as a fixed producer-gas through the outlet shown at the base ofthe back of the checker-chamber, whence it is led off to the point ofuse.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. In a gas-making apparatus, the combination of the generating chamber,asteam boiler therein in the path of the products of combustion, achecker-chamber communicating with the generating chamber and having anoutlet, and asteam-supcrheaterin the checkerchalnber, communicating withthe dome of said boiler and leading into the generating chamber,substantially as described.

2. In a gas-making apparatus, the combination of the generating chamber,a steam-boiler therein in the path of the products of combustion, achecker-chamber communicating with the generating chamber and having anoutlet, a steam-superheater in the checkerchamber, communicating withthe dome of the steam boiler, and having pipeconnections leading intothe generating-chamber and a hydrocarbon oil pipe leading into thecheckerchamber, substantially as described.

3. In a gas-making apparatus, the combina tion of the generatingchamber, a steam-boi ler comprising reservoirs at opposite sides of saidchamberconnected by tubes extending across the same, a checker-chambercommunicating with the generating chamber and having an outlet, and asteam-superheater in the checker-- chamber, communicating with the domeof said boiler and leading into the generating chamber, substantially asdescribed.

4. In a gas-making apparatus, the combin ation of the generatingchamber, a steam-boiler comprising a reservoir 7?. at one side, in saidtially as described.

5. In a gas-making apparatus, the combination of a generating chamber, asteam-boiler comprising a reservoir '11. at one side, in said chamber,and provided with a dome W, and intercomlnunicating reservoirs n and nsupported one above the other at the opposite side of said chamber andhaving tube-connections a with the reservoir 11,, extending across thegenerating chamber, a checker-chamber A communicating with thegenerating chamher and having an outlet, a steam-snperheater D in thechecker-chamber, communicating with the dome of the steam boiler andleading into the generating chamber, a fan I driven by an engine fedwith steam from said dome, tuyeres by which air from the fan is directedinto the generating chamber, and a pump G communicatipg with the dome tobe driven by steam therefrom and operating to discharge feed-water intothe reservoir n, substantially as described.
